This report is presented a s a record of data toward an
eventual analysis of racial variation in dermatoglyphics. It
is to be hoped that a broad comparison of races on this basis
may be eventually possible, but it will be necessary to continuc the accumulation of records on various populations,
perhaps from time to timc taking stock of progress a s has
been done recently by Steggerda, Steg-gerda and Lane for
the palmar features (Middle American Research Series, publication 7 , Tulane University, '36).
The material here treated represents a population not
hitherto investigated from the standpoint of dermatoglyphics.
The hilitwali a r e a Syrian mountain people, living in the southern Lebanon range. They a r e Moslems, but adhere t o the
Shiite sect rather than to the Sunni which is common to the
region. There a r e 138 subjects in the series, males and females
being in the proportion of about two to one; in view of the
small numbers the sexes a r e combined. The subjects are
mainly children in the government schools, the adult population having proved generally unsuitable for printing-on
account of extensive callouses.
The palmar features, main lines and patterns, a r e tabulated
in tables 1 and 2, their formulations following the methods of
Cummins et al. (Am. J. Phys. Anthrop., XII, '29).
The data on lines A and D have been further analyzed, to
determine the main-line index which has been suggested by
Cummins (Middle American Research Series, Tulane University, publication 7 , '36) a s a value denoting the degree of
slant of the general palmar configuration. F o r the 276 hands

DERMATOGLYPHICS IN PEOPLES O F NEAR EAST
As pointed out by Cummins and Steggerda (Am. J. Phys.
Anthrop., XX, ’35), the pattern types may be regarded aa
variants of ‘pattern intensity.’ The arch is not a pattern in
the strict sense of the term, while loops and whorls may be
regarded as levels of successively increasing pattern intensity. For statistical purposes arbitrary values are assigned to the pattern types : arch, 0; loop, 1; whorl, 2. The
complement of patterns in an individual is then converted into
the ‘index of pattern intensity’ by summating the values of

the ten patterns. The indices therefore range from 0, indicating ten arches, to 20, the value for ten whorls. The mean index
in the present series is 13.96 -e 0.20. As a matter of record,
providing for other statistical determinations such as the
dactylodiagram of Poll, the frequencies of pattern types on
separate digits are here recorded in table 3.
SUMMARY
Palmar main lines, axial triradii, palmar patterns and fingerprint patterns are analyzed in 138 Mitwali, a Syrian mountain population. It may be noted that the features present a
close relationship to another Lebanese series as well as to the
Rwala Arabs (unpublished data).
